Answer:
(a) 47.04 N
(b) 46 N
(c) 42.63 N
(d) 33.26 N
Step-by-step explanation:
mass of basket, m = 4.8 kg
(a) Normal force, N = mg = 4.8 x 9.8 = 47.04 newton
(b) Inclination of inclined plane, θ = 12°
Normal force, N = mg cosθ = 4.8 x 9.8 x Cos 12 = 46 Newton
(c) Inclination of inclined plane, θ = 25°
Normal force, N = mg cosθ = 4.8 x 9.8 x Cos 25 = 42.63 Newton
(d) Inclination of inclined plane, θ = 45°
Normal force, N = mg cosθ = 4.8 x 9.8 x Cos 45 = 33.26 Newton
